Method of manufacturing a graphene monolayer on insulating substrates

A method of manufacturing a graphene monolayer on insulating substrates from CVD graphene synthesis, wherein a metal foil (3) catalyst with a top graphene layer (1) and a bottom graphene layer (2) is obtained, by comprising the steps of: - Applying an adhesive tape (4) to the bottom graphene layer (2) deposited at the bottom of the metal foil (3) in the CVD graphene synthesis by a roller, - detaching the adhesive tape (4) and the bottom graphene layer (2) from the copper foil (3) via the application of heat, from 1°C up to 5°C higher than the release temperature of the adhesive tape (4) so that the adhesive layer (4) with the bottom graphene layer (2) can be removed, obtaining a metal foil (3) with a top graphene layer (2) sample, and - transfer the top graphene layer (1) onto a substrate (6) via a sacrificial protective layer (5).
